[Practice guideline 'Adenoid and tonsil disorders in secondary care'].

At the initiative of the Dutch Association of Otolaryngology and Head & Neck Surgery, in cooperation with the Dutch Institute for Healthcare Improvement (CBO), an evidence-based practice guideline was developed for adenoid and tonsil disorders in secondary care. (Adeno)tonsillectomy ((A)TE) is indicated in children with very frequent recurrent tonsillitis: 7 or more tonsillitises per year or 5 tonsillitises per year in the last 2 years. In children with moderately frequent recurrent tonsillitis, i.e. 4 to 6 tonsillitises per year, an (A)TE can be considered. If an (A)TE is performed under inhalation anaesthesia without intubation this must be done with the patient in the supine position. An (A)TE in children can be safely performed in day surgery. It is advisable to give preoperative information to both parents and children.
